[0015] To achieve the above objectives, the present invention also provides a high-speed wire harness welding system based on plasma aluminum foil stripping, comprising: The qualified cable acquisition module is used to identify the cable set and the plasma stripper. Based on the cable set, it identifies the test cable and multiple cables to be welded. It then mechanically strips the multiple cables to be welded to obtain multiple mechanically stripped cables. Based on the multiple mechanically stripped cables, it identifies multiple qualified cables.

[0017] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the aforementioned high-speed wire harness welding method based on plasma-stripped aluminum foil.
[0018] To address the problems described in the background art, this invention identifies a cable set and a plasma stripping machine. Based on the cable set, test cables and multiple cables to be welded are identified. This invention clarifies the production raw materials and core equipment, intelligently distinguishing between test samples for process optimization and main materials for mass production. This lays the foundation for subsequent refined process debugging and efficient production. Multiple cables to be welded are then mechanically stripped, resulting in multiple mechanically stripped cables. This invention uses mechanical methods to quickly and in batches remove the outer insulation from the cable ends, providing pre-processed semi-finished products for subsequent finishing. Multiple qualified cables are identified based on the results of the initial stripping. Quality screening removes damaged cables or those with unacceptable stripping lengths, ensuring consistent and reliable raw material quality for the next critical process. Multiple plasma treatment parameter sets are identified based on the plasma stripping machine. This embodiment of the invention provides options for finding the optimal treatment solution by pre-setting multiple alternative process parameter combinations (such as power, gas flow rate, and processing time) for the plasma surface treatment process. The optimal parameter set is identified based on test cables and multiple plasma treatment parameter sets. This embodiment of the invention uses reserved test cables to experiment with each parameter set, objectively determining the optimal process parameters by comparing treatment effects (such as cleanliness and surface activation), achieving process optimization at the lowest cost, and improving the stripping quality of high-speed wire harness shielding layers. Optimal parameter sets, a plasma stripping machine, and multiple qualified cables were used to identify several initially stripped cables. This demonstrates that the present invention applies optimized plasma parameters to mass production, performing fine cleaning and surface activation on the cable ends to thoroughly remove microscopic contaminants and improve the solderability of the welding surface. For each of the several initially stripped cables, the following operations are performed: performance testing is conducted on the initially stripped cables to obtain performance test scores. This demonstrates that the present invention achieves online quality monitoring during the production process by rapidly detecting and quantifying key performance aspects such as conductivity and plating integrity in each plasma-treated cable, improving the stripping quality of the high-speed wire harness shielding layer. The performance test scores are then summarized to obtain multiple performance test scores. This invention, through the aggregation of test results from all individual cables, forms a comprehensive data view of batch quality for assessing process stability and making release decisions. Based on multiple performance test scores and multiple preliminary stripped cables, multiple qualified stripped cables are identified. This invention automatically selects cables meeting performance standards based on scoring thresholds, ensuring that only high-quality processing results proceed to the final welding process. This strict quality control improves the stripping quality of high-speed wire harness shielding layers. For each qualified stripped cable, the following operations are performed: obtaining terminals, and welding the qualified stripped cable to the terminals to obtain a welded cable. This invention automates the welding of high-quality cables that have undergone rigorous pre-treatment to matching terminals.By forming a robust and reliable electrical connection, and consolidating the welded cables to obtain multiple welded cables, the high-speed wire harness welding is completed. It is evident that this embodiment of the invention improves the peeling quality of the shielding layer of the high-speed wire harness by producing batches of welded finished products with consistent quality, thereby improving the welding quality of the high-speed wire harness. Therefore, this invention can improve the peeling quality of the shielding layer of the high-speed wire harness, and thus improve the welding quality of the high-speed wire harness.

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0024] Reference Figure 1 The diagram shown is a schematic flowchart of a high-speed wire harness welding method based on plasma aluminum foil stripping according to an embodiment of the present invention. In this embodiment, the high-speed wire harness welding method based on plasma aluminum foil stripping includes: S1. Identify the cable set and plasma stripper, and based on the cable set, identify the test cable and multiple cables to be soldered.
[0025] For example, Xiao Zhang is an employee of a high-speed wire harness manufacturing plant. He needs to weld high-speed wire harnesses. So Xiao Zhang obtains a cable assembly for high-speed wire harness welding and a plasma stripper to facilitate subsequent processing of the cable assembly. He then uses the plasma stripper to peel off the aluminum foil, thereby completing the welding of the high-speed wire harness.
[0026] It should be explained that a cable assembly is a combination of multiple cables, wherein the cable is a coaxial cable, and the plasma stripper is a plasma cleaning machine; optionally, a Jinlai 30L vacuum plasma cleaning machine is used as the plasma stripper. The test cable refers to any single cable in the cable assembly, and the cable to be soldered refers to all cables in the cable assembly except the test cable.
[0027] S2. Mechanically strip multiple cables to be welded to obtain multiple mechanically stripped cables, and identify multiple qualified cables based on the multiple mechanically stripped cables.
[0028] It should be explained that the mechanical stripping of multiple cables to be welded refers to using mechanical stripping equipment (e.g., a laser cable stripper) to remove the insulation layers from both ends of multiple cables to be welded. The method of using mechanical stripping equipment (e.g., a laser cable stripper) to remove the insulation layers from both ends of multiple cables to be welded is existing technology and will not be elaborated here. Mechanically stripped cables refer to cables to be welded after mechanical stripping.
[0029] Specifically, the identification of multiple qualified cables based on multiple mechanical stripping methods includes: For each of the multiple mechanically stripped cables, the following operation shall be performed: The stripped surface and insulation layer cut were identified based on mechanical stripping of the cable. Tensile tests were performed on mechanically stripped cables to obtain the tensile index. Optical analysis of the peeled surface was performed to obtain the peeling smoothness; The cut of the insulation layer is inspected to obtain the flatness of the cut; The peel quality score is calculated based on tensile strength index, peel smoothness, and cut flatness, using the following formula: in, This indicates the peeling quality score. Indicates tensile strength index. Indicates peel smoothness. Indicates the smoothness of the cut. Represents the hyperbolic tangent function; The peeling quality scores are summarized to obtain multiple peeling quality scores; Multiple qualified cables were identified based on multiple stripping quality scores and preset stripping score thresholds.
[0030] It should be explained that, for ease of understanding, in this embodiment of the invention, the mechanically stripped cable is simplified to a slender cylinder, and the stripping surface is the top surface of the slender cylinder corresponding to the mechanically stripped cable. The insulation layer cut refers to the cut in the mechanically stripped cable where the insulation layer is exposed due to cutting. The tensile test of the mechanically stripped cable refers to testing its tensile strength using a tensile testing device (e.g., a tensile testing machine). The method for testing the tensile strength of the mechanically stripped cable using a tensile testing device (e.g., a tensile testing machine) is existing technology and will not be elaborated here. The tensile strength of the mechanically stripped cable is the tensile index. The stripping quality score reflects the effectiveness of the cable stripping process; the higher the stripping quality score, the better the stripping effect. It should be noted that in the calculation of the stripping quality score, only the numerical value is used, and its dimensions are not considered. Multiple qualified cables refer to multiple mechanically stripped cables corresponding to multiple stripping quality scores greater than or equal to the stripping score threshold. The stripping score threshold is set manually by the staff of the high-speed wire harness manufacturing plant based on the minimum stripping quality score of mechanically stripped cables that have passed the stripping test in the past. For example, if the minimum stripping quality score of mechanically stripped cables that have passed the stripping test in the past is 65, then the stripping score threshold is 65.
[0031] In detail, the optical analysis of the peeled surface to obtain the peel smoothness includes: Image acquisition is performed on the peeled surface to obtain an image of the peeled surface; The image of the stripped surface is converted to grayscale to obtain a grayscale image of the stripped surface; The binary image of the peeled surface is determined based on the grayscale image of the peeled surface and the preset grayscale threshold. Edge segmentation is performed on the binary image of the peeled surface to obtain a set of peeled surface edge points. This set includes multiple peeled surface edge points. Coordinates and edge points coordinate; Once the cable conductor radius is determined, the peel smoothness is calculated based on the edge point set of the peel surface and the cable conductor radius. The calculation formula is as follows: in, Indicates peel smoothness. Represents the first point in the set of edge points of the peeling surface. The edge point of the peeling surface. coordinate, Represents the first point in the set of edge points of the peeling surface. The edge point of the peeling surface. coordinate, Represents the first point in the set of edge points of the peeling surface. edge points of edge points coordinate, Represents the first point in the set of edge points of the peeling surface. The y-coordinate of the edge point of the peeling surface edge. This indicates the number of edge points on the peeling surface. Represents pi (π). Indicates the radius of the cable conductor.
[0032] It should be explained that the image acquisition of the peeled surface refers to taking an image of the peeled surface using an image acquisition device (e.g., a camera), and this image is the peeled surface image. The grayscale processing of the peeled surface image refers to converting each pixel in the peeled surface image to grayscale. The method for grayscale processing of the peeled surface image is existing technology and will not be described in detail here. The grayscale image of the peeled surface refers to the peeled surface image after grayscale processing. The binary image of the peeled surface refers to the grayscale image of the peeled surface after binarization; optionally, the grayscale threshold is 128.
[0033] For example, if the grayscale threshold is 128, then the relationship between the grayscale value of each pixel in the grayscale image of the stripped surface and 128 is determined. If the grayscale value of the pixel is greater than 128, then the grayscale value of the pixel is set to 255; otherwise, the grayscale value of the pixel is set to 0.
[0034] It should be understood that the edge segmentation of the binary image of the peeled surface refers to: using an edge detection algorithm (e.g., the Canny operator) to perform edge recognition on the region where the conductor is located in the binary image of the peeled surface, thereby obtaining the set of boundary pixels of the region where the conductor is located in the binary image of the peeled surface. The method of using an edge detection algorithm (e.g., the Canny operator) to perform edge recognition on the region where the conductor is located in the binary image of the peeled surface to obtain the set of boundary pixels of the region where the conductor is located is existing technology and will not be elaborated here. The set of boundary pixels of the region where the conductor is located in the binary image of the peeled surface is the set of edge points of the peeled surface. The boundary pixels are the edge points of the peeled surface. Coordinates refer to the x-coordinate of the boundary pixel, edge point The coordinates refer to the y-coordinates of the boundary pixels. The set of boundary pixels is a collection of pixels in the binary image of the stripped surface that satisfy the Canny operator detection conditions and are located at positions where pixel values change significantly. These pixels are typically located at the boundary between the conductor and the insulation layer. The conductor radius of the cable refers to the radius of the conductor in the cable. The stripping smoothness reflects the neatness of the edge of the wire core cross-section. The greater the stripping smoothness, the neater the edge of the wire core cross-section, and the better the processing effect of the wire stripping.
[0035] Specifically, the inspection of the insulation layer cut to obtain the cut flatness includes: The insulating layer cut was scanned and imaged to obtain multiple cut contour images; For each of the multiple cut contour images, perform the following operation: Edge extraction is performed on the cut contour image to obtain the edge boundary line; Identify the standard edge line, and determine the local flatness based on the edge boundary line and the standard edge line; By summing up the local flatness, multiple local flatness values are obtained; The cut surface smoothness is determined based on multiple local smoothness values, where the cut surface smoothness is the average of the multiple local smoothness values.
[0036] It should be explained that the scanning imaging of the insulation layer cut refers to: using an image acquisition device (such as a camera) along the circumference of the insulation layer cut on the mechanically stripped cable, taking an image of the insulation layer cut every certain angle (e.g., 5 degrees) until a full rotation is completed. The image of the insulation layer cut is the cut outline image. The method of taking an image of the insulation layer cut by using an image acquisition device (such as a camera) along the circumference of the insulation layer cut on the mechanically stripped cable, taking an image of the insulation layer cut every certain angle (e.g., 5 degrees) until a full rotation is existing technology and will not be described in detail here.
[0037] It is understood that the edge extraction of the cut contour image refers to: using an edge detection algorithm (e.g., the Canny operator) to identify the edges in the region where the boundary line between the conductor and the insulation layer is located in the cut contour image, thereby obtaining the boundary line between the conductor and the insulation layer in the cut contour image. This boundary line between the conductor and the insulation layer in the cut contour image is the edge demarcation line. Furthermore, the method of using an edge detection algorithm (e.g., the Canny operator) to identify the edges in the region where the boundary line between the conductor and the insulation layer is located in the cut contour image to obtain the boundary line between the conductor and the insulation layer in the cut contour image is existing technology and will not be elaborated upon here. The standard edge line refers to the boundary line between the conductor and the insulation layer in a mechanically stripped cable that has passed the stripping process.
[0038] Specifically, the determination of local flatness based on edge boundary lines and standard edge lines includes: The detection center is determined based on the edge boundary line, and the standard center and standard radius are determined based on the standard edge line. The registration boundary line is determined based on the detection center, the standard center, the edge boundary line, and the standard edge line. Feature points are extracted from the registration boundary line to obtain multiple edge feature points; For each of the multiple edge feature points, perform the following operation: The feature distance is determined based on the edge feature points and the standard circle center; The distance deviation value is calculated based on the characteristic distance and the standard radius, where the distance deviation value is the absolute difference between the characteristic distance and the standard radius; Summarize the distance deviation values to obtain multiple distance deviation values; Local flatness is calculated based on multiple distance deviation values, using the following formula: in, Indicates local flatness. Indicates the first of multiple distance deviation values One distance deviation value, Represents the natural constant. This represents the number of distance deviation values among multiple distance deviation values.
[0039] It should be explained that, for ease of understanding, this embodiment of the invention simplifies the mechanically stripped cable as a slender cylinder. The edge boundary line and the standard edge line can both be considered as part of the circumference of the circle on the top surface of the slender cylinder corresponding to the mechanically stripped cable. The detection center refers to the center of the circle corresponding to the edge boundary line, the standard center refers to the center of the circle corresponding to the standard edge line, and the standard radius refers to the radius of the circle corresponding to the standard edge line. The registration boundary line refers to the edge boundary line after aligning the detection center with the standard center of the standard edge line. Extracting feature points from the registration boundary line means randomly selecting multiple points from the registration boundary line; these multiple edge feature points are the multiple points randomly selected from the registration boundary line. The feature distance refers to the distance from the edge feature point to the standard center; optionally, the feature distance can be calculated using the distance formula between two points. Local flatness reflects the smoothness of the edge boundary line; the greater the local flatness, the smoother the edge boundary line, indicating a better stripping effect.
[0040] S3. Based on the plasma stripper, multiple plasma processing parameter sets were identified, and the optimal parameter set was identified based on the test cable and the multiple plasma processing parameter sets.
[0041] Specifically, the plasma stripping machine identifies multiple sets of plasma processing parameters, including: Based on the plasma stripper, the power generation control range, gas flow control range, and working distance control range were determined. The power control range is uniformly sampled according to a preset power sampling interval to obtain... One power generation test value; The gas flow control range is uniformly sampled according to the preset flow sampling interval to obtain... One gas flow rate test value; The working distance control range is uniformly sampled according to the preset distance sampling interval to obtain... One working distance test value; use Each power generation test value, Gas flow rate test values and Obtaining working distance test values There are several plasma processing parameter groups, among which... Each plasma processing parameter group includes: power generation test value, gas flow rate test value, and working distance test value.
[0042] It should be explained that the power generation control range refers to the adjustable range of the power of the plasma generated by the plasma stripper during operation; the gas flow control range refers to the adjustable range of the flow rate of the process gas (such as argon) inside the plasma stripper during operation; and the working distance control range refers to the adjustable range of the distance between the nozzle and the cable surface during operation. The power generation control range, gas flow control range, and working distance control range can all be obtained from the product technical manual provided by the plasma stripper manufacturer.
[0043] For example, if the power sampling interval is 100 watts and the power control range is 100-500 watts, then the power control range is uniformly sampled according to the preset power sampling interval to obtain... The power output test values are 100 watts, 200 watts, 300 watts, 400 watts, and 500 watts.
[0044] It should be understood that the gas flow control range is uniformly sampled according to a preset flow sampling interval to obtain... The method for measuring gas flow rate and the method of uniformly sampling the working distance control range according to a preset distance sampling interval to obtain The method for obtaining each working distance test value is the same as that for uniformly sampling the power control range according to the preset power sampling interval, to obtain... The method for generating power test values is the same and will not be repeated here. Optionally, the power sampling interval is 100 watts, and the flow rate sampling interval is 0.1m. 3 / s, with a sampling interval of 1 cm.
[0045] For example, if the three power generation test values are 100 watts, 200 watts, and 300 watts, and the three gas flow test values are 1 m³ / s... 3 / s, 1.1m 3 / s, 1.2m 3 / s, 3 working distance test values: 1 cm, 2 cm, 3 cm, then using 3 generating power test values of 100 W, 200 W, 300 W, and 3 gas flow rate test value: 1 m 3 / s, 1.1m 3 / s, 1.2m 3 / s, 3 working distance test values: 1 cm, 2 cm, 3 cm. The 27 plasma processing parameter sets obtained are: (100 W, 1 m 3 / s, 1 cm), (100 watts, 1 m 3 / s, 2 cm), ..., (300 watts, 1.2 m 3 / s, 2 cm), (300 watts, 1.2 m 3 / s, 3 cm).
[0046] Specifically, the optimal parameter set was determined based on the test cable and multiple plasma treatment parameter sets, including: Perform the following operation for each of the multiple plasma processing parameter groups: Samples were taken from the test cables to obtain cable samples; Mechanically peeling is performed on the cable sample to obtain a mechanically peeled sample; The target plasma stripper was identified based on the plasma processing parameter set and the plasma stripper. The mechanically peeled samples were subjected to plasma peeling using a target plasma peeling machine to obtain the processed samples; The processing score was determined based on the processed samples; The scores are aggregated to obtain multiple processing scores; The optimal processing score was determined based on multiple processing scores, where the optimal processing score is the largest processing score among the multiple processing scores. The plasma treatment parameter set corresponding to the best treatment score is taken as the best parameter set.
[0047] It should be explained that sampling the test cable refers to cutting a certain length (e.g., 5 cm) of the test cable from it; this certain length (e.g., 5 cm) of test cable is the cable sample. The method for mechanically stripping the cable sample is the same as the method for mechanically stripping multiple cables to be soldered, and will not be repeated here. The mechanically stripped sample refers to the cable sample after mechanical stripping. The target plasma stripping machine refers to a plasma stripping machine with the plasma generation power set to the generation power test value, the process gas flow rate set to the gas flow rate test value, and the distance between the processing head and the cable surface set to the working distance test value. Using the target plasma stripping machine to perform plasma stripping treatment on the mechanically stripped sample means: using the target plasma stripping machine to strip the shielding layer on the mechanically stripped sample; the method for using the target plasma stripping machine to strip the shielding layer on the mechanically stripped sample is existing technology and will not be repeated here. The treated sample refers to the mechanically stripped sample after plasma stripping treatment. The optimal parameter set refers to the plasma treatment parameter set corresponding to the optimal treatment score.
[0048] Specifically, the determination of the processing score based on the processed samples includes: The residual aluminum content of the treated sample was determined to obtain the residual aluminum mass. The loss angle was obtained by performing a loss test on the processed sample. The contact angle of the processed sample was measured to obtain the sample contact angle; The processing score is calculated based on the residual aluminum mass, loss angle, and sample contact angle, using the following formula: in, This indicates the processing of scores. Indicates the residual mass of aluminum. Indicates the loss angle. Indicates the contact angle of the sample. The residual mass is the preset baseline value. The preset loss tangent reference value, The preset contact angle reference value, Represents the tangent function. It is a natural exponential function.
[0049] It should be explained that the determination of residual aluminum in the treated sample refers to measuring the mass of aluminum in the treated sample using a residual element determination method (e.g., electron spectrometry). This method is existing technology and will not be elaborated further. The mass of aluminum in the treated sample is the residual aluminum mass. The loss test of the treated sample refers to measuring the dielectric loss angle of the treated sample using a loss testing device (e.g., a dielectric loss meter). This method is existing technology and will not be elaborated further. The dielectric loss angle of the treated sample is the loss angle. The contact angle measurement of the treated sample refers to measuring the wetting angle of the treated sample using a contact angle measuring device (e.g., an automatic contact angle meter). This method is existing technology and will not be elaborated further. The wetting angle of the treated sample is the sample contact angle.
[0050] S4. Based on the optimal parameter set, plasma stripper, and multiple qualified cables, multiple preliminary stripped cables were identified.
[0051] It should be explained that the identification of multiple initially stripped cables based on the optimal parameter set, the plasma stripper, and multiple qualified cables refers to the following: First, the power of the plasma generated by the plasma stripper during operation is set to the plasma generation power in the optimal parameter set; the flow rate of the process gas (such as argon) inside the plasma stripper during operation is set to the gas flow rate test value; and the distance between the nozzle and the cable surface of the plasma stripper during operation is set to the working distance test value, thus obtaining the target plasma stripper. Then, the target plasma stripper is used to strip the shielding layer of multiple qualified cables. Multiple initially stripped cables refer to multiple qualified cables whose shielding layer has been stripped.
[0052] S5. For each of the multiple initially stripped cables, perform the following operations: conduct performance tests on the initially stripped cables, obtain performance test scores, summarize the performance test scores, and obtain multiple performance test scores.
[0053] In detail, the performance test performed on the initially stripped cable to obtain a performance test score includes: Preliminary cable stripping confirmed the presence of exposed conductors and untreated insulation. The insulation resistance value is obtained by measuring the resistance of the bare conductor and the untreated insulation layer. Loss tests were performed on the initially stripped cable to obtain the cable loss angle. Obtain a polished copper plate, perform a reflection intensity test on the polished copper plate, and obtain the standard reflection intensity; The reflection intensity of the exposed conductor is obtained by testing its reflection intensity. The performance test score is calculated based on the insulation resistance value, cable loss angle, standard reflection intensity, and conductor reflection intensity. The calculation formula is as follows: in, This indicates the performance test score. Indicates the insulation resistance value. This indicates the preset standard insulation resistance value. Indicates the cable loss angle. Indicates the reflectivity of the conductor. Indicates standard reflection intensity. This represents the tangent function.
[0054] It should be explained that exposed conductors refer to the conductors exposed after the insulation layer is stripped in the initial stripping of the cable, while untreated insulation refers to the insulation layer that has not been stripped in the initial stripping of the cable. The resistance measurement of the exposed conductors and untreated insulation refers to measuring the resistance between the exposed conductors and untreated insulation using a resistance measuring device (e.g., a multimeter). The method of measuring the resistance between the exposed conductors and untreated insulation using a resistance measuring device (e.g., a multimeter) is existing technology and will not be elaborated here. The resistance between the exposed conductors and untreated insulation is the insulation resistance value.
[0055] It should be understood that the method for obtaining the cable loss angle by performing loss testing on the initially stripped cable is the same as the method for obtaining the loss angle by performing loss testing on the processed sample, and will not be repeated here.
[0056] It is understood that a polished copper plate refers to a copper sheet whose surface has been polished. The test of the reflectance intensity of the polished copper plate involves irradiating the plate with a light source (e.g., a laser) and measuring the intensity of the reflected light from the plate's surface using a light intensity receiving device (e.g., a photoelectric sensor). Both the method of irradiating the plate with a laser and the method of measuring the intensity of the reflected light are existing technologies and will not be elaborated upon here. The intensity of the reflected light from the polished copper plate surface is the standard reflectance intensity.
[0057] It should be understood that the method for obtaining the conductor's reflection intensity by performing a reflection intensity test on the bare conductor is the same as the method for obtaining the standard reflection intensity by performing a reflection intensity test on the polished copper plate, and will not be repeated here. The performance test score reflects the electrical performance of the initially stripped cable. The higher the performance test score, the better the electrical performance of the initially stripped cable. The standard insulation resistance value is set manually by the power substation staff based on the average resistance between the bare conductor and the untreated insulation layer in multiple historically qualified initially stripped cables. For example, if the average resistance between the bare conductor and the untreated insulation layer in multiple historically qualified initially stripped cables is 1000Ω, then the standard insulation resistance value is 1000Ω.
[0058] S6. Based on multiple performance test scores and multiple preliminary stripping of cables, multiple qualified stripping cables were identified.
[0059] It should be explained that the confirmation of multiple qualified stripped cables based on multiple performance test scores and multiple preliminary stripped cables means: firstly, according to a preset performance score threshold, multiple performance test scores greater than or equal to the performance score threshold are selected from the multiple performance test scores; then, the preliminary stripped cables corresponding to the multiple performance test scores greater than or equal to the performance score threshold are considered as multiple qualified stripped cables. The performance score threshold is a value manually set by the power substation staff; optionally, the performance score threshold is 85.
[0060] S7. For each of the multiple stripped and qualified cables, perform the following operations: obtain a terminal, weld the stripped and qualified cable to the terminal to obtain a welded cable, summarize the welded cables to obtain multiple welded cables, and complete the high-speed wire harness welding.
[0061] It should be explained that the terminal is a coaxial connector, and optionally, the Hongfa MMCX series coaxial connector can be used as the terminal. The phrase "soldering the stripped cable to the terminal" refers to using welding equipment (e.g., a laser welding machine) to weld the stripped cable to the terminal. This method of using welding equipment (e.g., a laser welding machine) to weld the stripped cable to the terminal is existing technology and will not be elaborated here. The welded cable refers to the stripped cable after the terminal has been soldered to it.
[0062] For example, once multiple welding cables are obtained, Xiao Zhang can then assemble them to complete the high-speed wire harness welding.
[0063] To address the problems described in the background art, this invention identifies a cable set and a plasma stripping machine. Based on the cable set, test cables and multiple cables to be welded are identified. This invention clarifies the production raw materials and core equipment, intelligently distinguishing between test samples for process optimization and main materials for mass production. This lays the foundation for subsequent refined process debugging and efficient production. Multiple cables to be welded are then mechanically stripped, resulting in multiple mechanically stripped cables. This invention uses mechanical methods to quickly and in batches remove the outer insulation from the cable ends, providing pre-processed semi-finished products for subsequent finishing. Multiple qualified cables are identified based on the results of the initial stripping. Quality screening removes damaged cables or those with unacceptable stripping lengths, ensuring consistent and reliable raw material quality for the next critical process. Multiple plasma treatment parameter sets are identified based on the plasma stripping machine. This embodiment of the invention provides options for finding the optimal treatment solution by pre-setting multiple alternative process parameter combinations (such as power, gas flow rate, and processing time) for the plasma surface treatment process. The optimal parameter set is identified based on test cables and multiple plasma treatment parameter sets. This embodiment of the invention uses reserved test cables to experiment with each parameter set, objectively determining the optimal process parameters by comparing treatment effects (such as cleanliness and surface activation), achieving process optimization at the lowest cost, and improving the stripping quality of high-speed wire harness shielding layers. Optimal parameter sets, a plasma stripping machine, and multiple qualified cables were used to identify several initially stripped cables. This demonstrates that the present invention applies optimized plasma parameters to mass production, performing fine cleaning and surface activation on the cable ends to thoroughly remove microscopic contaminants and improve the solderability of the welding surface. For each of the several initially stripped cables, the following operations are performed: performance testing is conducted on the initially stripped cables to obtain performance test scores. This demonstrates that the present invention achieves online quality monitoring during the production process by rapidly detecting and quantifying key performance aspects such as conductivity and plating integrity in each plasma-treated cable, improving the stripping quality of the high-speed wire harness shielding layer. The performance test scores are then summarized to obtain multiple performance test scores. This invention, through the aggregation of test results from all individual cables, forms a comprehensive data view of batch quality for assessing process stability and making release decisions. Based on multiple performance test scores and multiple preliminary stripped cables, multiple qualified stripped cables are identified. This invention automatically selects cables meeting performance standards based on scoring thresholds, ensuring that only high-quality processing results proceed to the final welding process. This strict quality control improves the stripping quality of high-speed wire harness shielding layers. For each qualified stripped cable, the following operations are performed: obtaining terminals, and welding the qualified stripped cable to the terminals to obtain a welded cable. This invention automates the welding of high-quality cables that have undergone rigorous pre-treatment to matching terminals.By forming a robust and reliable electrical connection, and consolidating the welded cables to obtain multiple welded cables, the high-speed wire harness welding is completed. It is evident that this embodiment of the invention improves the peeling quality of the shielding layer of the high-speed wire harness by producing batches of welded finished products with consistent quality, thereby improving the welding quality of the high-speed wire harness. Therefore, this invention can improve the peeling quality of the shielding layer of the high-speed wire harness, and thus improve the welding quality of the high-speed wire harness.
